Cannot create a new document using UIDocumentBrowserViewController in iOS 13 Simulator

FB7250982
After tapping the plus icon in UIDocumentBrowserViewController in iOS 13 Simulator to create a document,
both in the nav bar as well as in the main content (when Browse / On my iPad is selected), all that happens is that the following error message is printed in the Xcode console:
```

When the same app is run on a real device, everything works as expected.

Steps to reproduce:
1. Open the attached Xcode project and run in iOS 13 Simulator (e.g. iPad Pro 11")
2. Tap the "+" icon in the nav bar to create a new document
The attached project is basically just a "Document Based App" template with implemented documentBrowser(_ controller:didRequestDocumentCreationWithHandler:) method
Expected behaviour:
I expected a new document would be created and presented from the document browser.
Actual behaviour:
Nothing is presented from the document browser and the following message is printed in the Xcode console:
